UNITE. STATES JOE JAMES, OF BEGXVNWOOD, MISElOURI.

BOX OPENER.

Application filed December 29, 1824. Serial No. 758,753.

This invention relates to improvements in box openers and contemplates the provision of a tool especially adapted for opening pasteboard bones and cartons or the like.

An objeit of the invention is to provide guiding means upon the lower portion thereof which is adapted to be received upon the under side of the cover of a, pasteboard box or the like and to have supported within a groove provided therein. a cutting blade or disk which may travel therewith in order to cut or rip a cover of the pasteboard box or the like so that the same may be readily and easily opened and without injuring any of the articles contained therein.

A further object of the invention is the provision of a tool which is so constructed and owing to its simplicity of parts that the same may be manufactured in great numbers and sold at a very nominal cost and owing to the fact that pasteboard boxes or cartons are being used in constantly increasing numbers in various sorts of business and that the tool now utilized in opening paper boxes and cartons or the like is a sharp knife which frequently injures the articles contained within the containers.

With the above and other objects in View, the invention further includes the following novel features and details of construction, to be hereinafter more fully described, illustrated in the accompanying drawing and pointed out in the appended claims.

In the drawing Figure 1 is a perspective of the tool per Figure 2 is a top plan sectional \lQW of the invention and showing the same in an openting position and applied to the top of a pastehoard container, carton or the like.

.eferringto the drawing in detail, wherein like characters of reference denote corresponding parts, the reference character 10 indicates a handle which may be formed of wood or constructed of any suitable material and which includes upon the inner end portion thereof a. ferrule 11 in order to prevent this end from splitting when the inner end portion of the tool is driven therein.

This tool includes a main shaft 12 which has the inner end portion thereof substantially reduced and pointed as at 13 in order that the same may readily and easily be driven within the ferruled end portion of the handle 10 and which main shaft 11 is substantially ofiset as at 1i and extends downwardly therefrom and terminates in a bifurcated end portion which spaced parallel legs 15. Pivotally mounted between those legs 15 and adjacent the outer end portions thereof is a cutting disk 16 constructed of cutlery steel and having the outer periphery thereof substantially sharpened in order to easily cut the top of pasteboard bones, cartons or the like.

In order to provide means for guiding this tool along the upper portion of acardboard box top there is provided a guiding member 17 which includes a substantially ofiset portion 18 and which portion is received between'the inner end portion of the parallel legs 15 and rigidly secured therebetween through the instrumentality of a rivet 19; the opposite end portion or forwardly extending portion of the guiding portion 17 includes a slotted portion 20 and which is adapted to receive therein the lower side of the cutting wheel or disk 16 and allow the same to extend beyond the lower side thereof an appreciable distance. The forward end portion of the guiding member 17 is sharpened as at 21 and is substantially upwardly beveled so that when the same is inserted or stuck through a top of the cardboard boX or the like and the same is brought back in a same plane with the top of a boX or the like that the said pointed portion 21 will not engage, demolish or in any way injure any of the articles contained within the cardboard box or carton and the li re.

In the use and operation of the present invention it will be clearly apparent that upon inserting the pointed portion 21 within the top of a box or the like and bringing the same in the same plane with the upper portion of the box and pushing forwardly upon the handle portion 10 that the top of the box will be received between the cutting blade and the upper side of the guiding member 17 and be cut or ripped without injuring any of the articles contained within the pasteboard box, carton or the like.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is hereincludes in reserved to make such changes as properly fall within the scope of the appended claims.

Having thus described my invention what is claimed is:

1. A box opener of the character described comprising a rectangularly shaped substantially offset bar having its inner end portion substantially reduced and sharpened, a tool handle receiving the reduced sharpened end portion of the bar therein, the offset forwardly extending end portion of said bar being substantially bifurcated, a rotatable cutting disk pivotally secured between the spaced parallel legs of the bifurcation and adjacent the outer end portions thereof, and guiding means extending from the forwardly extending bifurcated end portion and in the same line of proximity therewith.

2. A box opener of the character described comprising a substantially oifset rectangular shaped bar member having its inner end portion substantially reduced and sharpened, a ferruled tool handle received on this sharpened end portion, the forwardly extending end portionof the bar member being bifurcated and providing a pair of spacedparallel legs thereon, a rotatable cutting disk pivotally secured between the spaced parallel legs. and adjacent the outer end portions thereof, and a substantially offset guiding member having its upper end portion rigidly secured between the spaced parallel legs, and its opposite end portion extending in spaced parallel relation and directly beneath the spaced parallel legs of the bar member.

3. A box opener of the character described comprising a rectangular shaped substantially offset bar member having its inner. endportion substantially reduced and sharpened, a ferrule'd tool handle receiving the reduced sharpened end portion of the bar member therein, the forwardly extending end portion of the bar member being bifurcated and providing a pair of spaced parallel legs thereon, a rotatable cutting disk pivotally mounted between the spaced parallel legs and adjacent the outer end portions thereof, and a substantially offset guiding member having alongitu'dinal slot therein and receiving the lower edge of the rotatable cutting disk therein and having its upwardly extending portion rigidly secured between the spaced parallel legs and adjacentthe inner end portions thereof substantially as set forth.

In testimony whereof, I afliX my signature.

JOE JAMES.
